Answer:
x=6, y = -9
Step-by-step explanation:
6x + 2y = 18
-4x - 2y = -6
Add the two equations together to eliminate y
6x + 2y = 18
-4x - 2y = -6
------------------------
2x +0y = 12
Divide by 2
2x/2 = 12/2
x = 6
Then find y
6x+2y = 18
6*6 +2y = 18
36+2y = 18
Subtract 36 from each side
36+2y-36 = 18-6
2y = -18
Divide by 2
2y/2 = -18/2
y = -9
Answer:
The median is usually preferred in these situations because the value of the mean can be distorted by the outliers. However, it will depend on how influential the outliers are. If they do not significantly distort the mean, using the mean as the measure of central tendency will usually be preferred.
